Dioxide Materials introduces water electrolyser technology

As published by By Molly Burgess on Jul 18, 2019 Water electrolysers are being developed as a method of storing renewable energy as a route to creating hydrogen for fuel cell cars as well as for the production of renewable fuels and chemicals. Alkaline water electrolysers (AWE) are particularly popular as they can operate using base metal catalysts instead of needing precious group metal … Read More

The Partnership: Turning Carbon Dioxide Into Useful Products

ARPA-E funded two separate companies – LanzaTech and Dioxide Materials – working on two separate technologies that ultimately joined forces to target the same problem: how do we make use of carbon dioxide instead of releasing it to the atmosphere? The partnership between these two teams has resulted in a potentially game-changing development in how we convert and utilize a … Read More
